Delayed Release Tie-In: In the United Kingdom, Cadbury Easter eggs and chocolate bars themed after the second movie, which had "Only at cinemas" printed on the packaging, were sold for the 2020 Easter season. They became dated after the movie was delayed into 2021.
Fake Brit: We have Domhnall Gleeson (Irish), Rose Byrne, Elizabeth Debicki, and Margot Robbie (Australian) and Sam Neil (New Zealand) as English characters.
Fake Scot: Sia (Australian) as Scottish Mrs. Tiggy Winkle.
Follow the Leader: Modern adaptation of a classic animal character from a British children's book? Clearly following the lead set by Paddington (2014).
Release Date Change: The Runaway had no less than ten in the United States. Initially set for April 3, 2020, Easter weekend, it was initially postponed to August 7 due to the COVID-19 Pandemic. When that proved to be insufficient, it was moved again to January 15, 2021 in a series of moves within Sony’s entire slate. That proved to be still not enough and the film was again moved, this time with a February 12, 2021 release in the United Kingdom, with a delayed release in Australia on June 10 and June 18 in the United States. Several date changes later, it ultimately released first in Australia/New Zealand on March 25, 2021, not hitting the UK until May 17; it finally released in the US on June 11 after a number of last-minute shifts to avoid competing directly with Luca and The Boss Baby: Family Business.
The series
The Merch: There have been a number of plush toys, as well as model figures, playsets and a plate/silverware set. Additionally, Peter Rabbit has long been featured on a line of fruit/vegetable snack pouches known as Peter Rabbit Organics. When this series began airing, the packaging on these was changed to feature Peter's look from the television series, as opposed to the original Beatrix Potter book-style illustrations.
Neither Nick Jr. Asia nor CBeebies Asia are airing it in the Asian region. Furthermore, despite the popularity of Peter Rabbit himself in Japan, it was never aired in that country until 2021 when it was released on the Anilog YouTube channel, mainly since Nickelodeon is no longer on Japanese TV stations and could also fall into a similar situation as Nick Jr. Asia and CBeebies did. This may have something to do with the fact that Nick owns the rights to the show only for North and South America according to this Viacom distribution site. It also explains why the show airs on non-Viacom owned networks outside of the mentioned territories.
Some of the toys, such as the Cottontail plush and the talking Lily and Benjamin, are U.K.-exclusives, though the talking Peter is available in the U.S., albeit in a slightly different version.
